Eye Strain
Eye strain is commonly associated with blurred vision and the inability to keep the eyes open. It may happen when driving, staring at screens or reading for long periods. While eye strain usually resolves itself when the person rests, it's worth seeing an optometrist if the problem persists.
Eye strain can also cause dark circles, as it can affect the blood vessels around the eyes. These may become enlarged and more visible, which can result in the appearance of dark circles.1Sheth, Pratik B., et al. ‘Periorbital Hyperpigmentation: A Study of Its Prevalence, Common Causative Factors and Its Association with Personal Habits and Other Disorders.’ PubMed Central (PMC), Mar. 2014, www.ncbi.nlm.nih.gov/pmc/articles/PMC3969674/
